Abstract

A bag folding structure of a safe air bag solves the problem that the present bag folding mode may lead the safe air bag to directly rush at passengers after the safe air bag is opened and cause serious damage. The bag folding structure comprises an air bag, and is characterized in that the front and the rear ends of the air bag are folded inwards; the left and the right ends adopts inward-outward winding shapes; and the transitional parts of the middle part of the air bag and the left and right inward-outward winding parts are doubled-up. Based on the principle that the air bag fabric with different folding modes have different resistance forces to airflow, different resistance forces to airflow in different directions of the air bag can be realized through bag folding, and different expand rates at the periphery of the air bag are achieved. By adopting the bag folding structure of the safe air bag, the air bag can expand upwards and towards the periphery at the beginning and then expand in the middle, so that the airflow of the air bag towards the passengers bears more resistance force and the expand rate in the direction is decelerated, thereby reducing impact strength of the air bag to the passengers during expansion process, achieving ideal expand effect, reducing injury of the passengers, and better protecting the passengers.

Description

Safety air bag is folded bag constructions

Technical field

The utility model relates to a kind of air bag device that is provided on the automobile, and particularly a kind of safety air bag is folded bag constructions.

Background technology

The starting stage of air-bag deployment can go out very big energy in abrupt release.If the occupant at the stages of deployment contact air bag of air bag, directly rushes at the occupant after inappropriate folded bag mode can make air-bag deployment, cause serious injury.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that prior art exists, and a kind of occupant injury nearer apart from air bag that reduce is provided, and the occupant of normal sitting position is provided the folded bag constructions of safety air bag of effective protection.

The utility model is achieved in that

It comprises an airbag, and described airbag front and back ends is the folded inward shape, and left and right two ends are the inside and outside shape that unrolls, and the unroll transition position at position of airbag middle part and left and right inside and outside is the doubling shape.

Above-mentioned safety air bag is folded bag constructions, and the forward and backward two ends of described airbag are multiple rugosity.

Above-mentioned safety air bag is folded bag constructions, and described airbag front end is multiple rugosity, rear end and is the inside and outside shape that unrolls, and the end of airbag rear end is the snakelike shape that unrolls.

The utility model has the advantages that:, therefore can make the resistance difference of the different directions of airbag, and then make the development rate difference around the airbag by folded bag to air-flow because the different folding mode of airbag cloth is different to the size of the resistance of air-flow.The air-flow that the folded bag constructions of this safety air bag faces toward on this direction of occupant airbag is subjected to bigger resistance, airbag upwards and is all around launched earlier, carrying out the centre again launches, thereby airbag is slowed down at the development rate of this direction, reach desirable expansion effect, reduce in the airbag deployment process instant impact, thereby reduce air bag, make the occupant be subjected to littler injury launching the injury of starting stage to the occupant to the occupant.The folded bag constructions of this safety air bag is compared with general folded bag and is uncomplicated, and does not need other more auxiliary devices just can realize; This device does not need the change of vehicle structure; This device is compatible mutually with current air bag system; Only use current ignition circuit can realize high protective value; Satisfy customer's requirement more and more higher to passive security.

The specific embodiment

Embodiment 1:

As Fig. 1～shown in Figure 5, the utility model has an airbag 1, admission port place at airbag 1 is provided with pressing plate 2, described airbag 1 front and back ends 105,106 is multiple inwards rugosity, left and right two ends 101,102 are the inside and outside shape that unrolls, and the unroll transition position 103,104 at position of airbag 1 middle part and 101,102 inside and outsides, left and right two ends is the doubling shape.

Folded bag process is as follows:

Step 1: earlier airbag 1 admission port is tiled downwards (as shown in Figure 6); Step 2: fill in inwards from airbag 1 forward and backward two ends 105,106 but distance not too wide (Fig. 3), the width after fill in just for airbag fold bag after a final width; Step 3: again airbag 1 and arranged on left and right sides 101,102 to last volume (as Fig. 5); Step 4: at last the part of rolling up in the last step upwards turn over (as Fig. 1).

Embodiment 2:

As Fig. 7～shown in Figure 10, the utility model has an airbag 1, is provided with pressing plate 2 at the admission port place of airbag 1, and described airbag 1 front end 105 is multiple inwards rugosity, rear end 106 and is by lining unroll the outward shape and the end 107 snakelike shapes that unroll of rear end 106.The left and right two ends 101,102 of airbag 1 are the inside and outside shape that unrolls, and the unroll transition position 103,104 at position of airbag 1 middle part and 101,102 inside and outsides, left and right two ends is the doubling shape.

Folded bag process is as follows:

Step 1: earlier airbag 1 admission port is tiled downwards; Step 2: fill in inwards but the width of distance after too wide (as Figure 10) fill in just is airbag half of final width after folding bag from airbag 1 front end; Step 3: roll over after the part again volume (as Fig. 9) inwards from airbag 1 rear end inwards; Step 4: the airbag both sides to last volume; Step 5: at last the part of rolling up in the last step upwards turn over (Fig. 7).
